CAR-STARTER.

SPECIFICATION forming part of Letters Patent No. 367,531,dated August 2, 1887.

Application filed Augustl, 1886. Renewed July 5, 1887'. Serial No. 943.412. (No model.)

.To aZZ whom it may conccrn.-

Be it known that I, JOHN M. LINSCOTT, of Worcester, in the county' of XVorcester and State of Massachusetts, have invented certain new and useful Improvements in Car-Starters; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters of reference marked thereon,which form a part of this specification, in which- Figure 1 is a top plan. Fig. 2 is aside sectional elevation. Fig. 3 is a side elevation,

with parts broken out to show the working parts.

Same letters show like paris.

My invention relates to car-starters, or 'to devices to increase the ease of starting horsecars and other vehicles.

a is the forward shaft of a car. On this shaft I first place the framework b. This frame-work is loose on the shaft a, so that the shaft revolvcs in the holes c,n1ade through the framework. This framework carries apawl, d. This pawl slides upwardly and downwardly in grooves on the iusides of the parts of the framework b. This is seen at Fig. 2. Between the two parts or sides of the framework b, and rigdly on the shaft a, Iplace the ratchet e. Into the teeth of this ratchet works the pawl d. On the back side of the framework bis a table, f.

`Projecting from the pawl d on the back side is the tongue g. This tongue is connected with the pawl d, and lifts it upwardly by resting on the tablef, as will be hereinafter set forth.

Pivoted into the side of the caylat 72', is a horizontal lever,'. This lever is pivoted atj to the draw-bar k. nected to the animals drawing the car. The leveri has a link, Z, which is connected also with the framework b. Being a loose link, it also allows the body of the car to rise or fall on its springs without binding.

The pawl rests in the teeth' of the ratchet e when the parts are in the position seen in Fig. 1, which is the position in which they are before the horses have begun to draw. When the animals begin to draw, the draw-bar k is pulled forwardly,and the horizontal lever i The draw-,bar k is con-- also. This motion of the horizontal lever turns the framework I) also forwardly or toward the animals and on the shaft a, The pawl d being .in the teeth of the ratchet e, and being moved as the framework is moved, turns the ratchet e, and so revolves the shafta and its car-wheels, and so facilitates the starting of the car. When the horses stop, the spring m, connected with the tablef and to some rigid part of the car-frame, draws the framework b back into the position seen in Fig. 3. When this takes place,the tongue g strikes the tablefiand this lifts the pawl d out of the ratehet and allows of the movement of the shaft a backwardly, if desired. wardly when the pawl is in the teeth of the ratchet e.

a is a brake to be operated by the driver s foot, and set in the floor of the car-platform. When the pressu re of the foot is taken off from it,it is lifted by the spring o. XVhen the drawbar is pulled forwardly and it is desired to stop 011 a hill or other place, the driver places his foot on the brake n. The braken at itslower end works into the teeth seen on the draw-bar Ic, and so holds it in the position it may be when the brake is forced down onto it. If the draw-bar is drawn forwardly, then the framework I is also tipped forwardly, the pawl d is in the teeth of the ratchet e, and so the forward wheels of the car (those on the shaft (e) are prevented from revolving backward. Remove the pressure from the brake u, back the horses slightly, and the contrivance becomes a starting contrivance again, as before described.

hat I clain as my inv'eutio, and desire to secure by Letters Patent, is-- 1. The combination of the shaft a, framework I), ratchet e, tablef, pawl d, and tongue g, spring m, draw-bar 7.7, horizontal lever i, and link Z, for a ear-starter,asl1erein set fort-h.

2. The combination of the brake n, spring c, the tootled draw-bar k, framework Z,paw1 d, ratchet e, and link Z, as a device to brake up or stop or holda car, as herein set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses. r
